Right, now I need to send automatically e-mails in this situation, It´s possible of course:
Suppose that students subscribe at training course "advanced Moodle configuration" (for example), well, when one week or lesson pass, unlock automatically next learm session. right?
I need that at this students, when unlock next lesson, Moodle, send an information e-mail automatically with some text, for example: "You have a New lesson unlocked" or "Have a new lesson: Theme configuration"
Have I explained it correctly?
